Women's Biological Clock Revealed: Hormone May Predict Age At Menopause

Age at menopause may now be predicted more realistically according to a new study. The study revealed that anti-Müllerian hormone (AMH) levels are related to the onset of menopause and are able to specify a woman's reproductive age more accurately than chronological age alone. The levels of AMH in the blood reflect the number of small follicles present in a woman's ovaries. This follicle stock enables reproduction by ensuring monthly ovulations. Depletion of the stock leads to menopause, which normally occurs between 40 and 60 years of age.
